I used to do bank shots with a .22 LR rifle using old yard sale pans, and glass beer bottles. I could get 2 with one shot most every time. The best I ever did was breaking 4 bottles. I tried to get 3 many times. Though the bullet was so fragged, and chewed up it would usualy just knock the third bottle over without breakig it.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
